* EPS C$0.28 vs C$0.25 a year earlier
* Revenue down 4 percent at C$910.4 mln
TORONTO, April 28 (Reuters) - CGI Group Inc (GIBa.TO), Canada's biggest computer consulting company, posted a 4.9 percent increase in quarterly profit on Wednesday, driven by improvements in its systems integrations and consulting business.
Net profit rose to C$81.6 million, or 28 Canadian cents a share, in the second quarter ended March 31 from C$77.8 million, or 25 Canadian cents a share, a year earlier.
Analysts had expected a profit of 27 Canadian cents a share, according to Thomson Reuters I/B/E/S.
Revenue fell 4 percent to C$910.4 million, hurt by unfavorable foreign exchange fluctuations.
The Montreal-based company said it had signed C$1.1 billion in new contracts in the quarter. At the end of March, its backlog of signed orders stood at C$11.4 billion.
CGI does the bulk of its business in Canada, which represents an estimated 55 percent to 60 percent of sales, followed by the United States, at 30 percent to 35 percent. About 5 percent to 10 percent of its business comes from outside those markets. ($1=$1.01 Canadian) (Reporting by Euan Rocha and Susan Taylor; Editing by Lisa Von Ahn)
